Hi Bottomlyne, and welcome to the Wine Board. Can't find any sources for these wines in the U.S. If you are willing to look at overseas sources go to www.wine-searcher.com and look world wide or even just at the UK and Germany where most of the sources are.

If you want alternatives, go to www.southernwines.com. They have sixteen different SA Shirazes available, and can surely recommend one close to your Zandvliet.
